To provide a method which enables the manufacture of a skin-integrated foam molded article by accurately positioning the skin, easy demolding of the skin-integrated foam molded article, and reduction of a section to be cut after demolding.

A slide mold 15 slidable to the cavity inner and outer direction Q1 crossing the demolding direction E1 of the skin-integrated foam molded article is provided, and a skin end locking plate 21 having a projection 25 for locking the skin end formed on the surface is projected on an overlapped surface with a lid mold of a cavity mold toward the cavity inward crossing the demolding direction and provided so as to overlap with a lid mold side surface of the slide mold 15. When the slide mold 15 slides to the outward of the cavity, and an undercut shape is eliminated, a cavity inward end part side 23 of the skin end part locking plate 21 becomes a state projecting to the cavity inward, and the projection part can be turned to the demolding direction when being pressed to the demolding direction.
